Carrier Corporation is a subsidiary of the United Technologies Corp. (UTC),

which ranks the 150th in Fortune Top 500 in 2011 and has its operations in

aerospace and building systems industries all over the world. From the time the

founder Dr. Carrier invented the first system of modern air conditioning in 1902,

Carrier has been the world leader in the air conditioning industry with its products

and system solutions supplied to numerous famous buildings, and up to now, the

network of distribution cover more than 170 countries all over the world. In 2011,

Carrier ranked top in the HVAC industry field with its sales revenue of US $12

billion.

In China, there are 6 Carrier factories which have more than 2500 employees. As

the world-class factory, Carrier has a number of technically advanced production

lines, manufacturing commercial and residential chillers, compressors and

air-side products. A wide range of products are able to meet diversified require-

ments of different customers. The global R&D center located in Shanghai has the

capability of developing several major projects in the same time, with many

advanced technical patents awarded to support Carrier stay most competitive in

terms of technology advantage in the HVAC industry.

Carrier China

In 1998, Time magazine named Dr. Carrier one

of its 20 most influential builders and titans of

the 20 thcentury.

30RB/RQ 039S-160S

Features

Simplified electrical connections

- A single power supply point without neutral

- Main disconnect switch with high trip capacity

- Transformer for safe 24 V control circuit supply included

Fast commissioning

- Systematic factory operation test before shipment

- Quick-test function for step-by-step verification of the

instruments, electrical components and motors

Quiet operation

Compressors

- Low-noise scroll compressors with low vibration level

- The compressor assembly is installed on an

independent chassis and supported by anti-vibration

mountings

- Dynamic suction and discharge piping support,

minimizing vibration transmission (Carrier patent)

Condenser section

- Vertical condenser coils

- Protection grilles on anti-vibration mountings to protect

the heat exchanger against possible shocks.

- Low-noise latest-generation Flying Bird IV fans (Carrier

patent) , made of a composite material are now even

quieter and do not generate intrusive low-frequency

noise

- Rigid fan installation for reduced start-up noise (Carrier

patent)

Economical operation

Increased energy efficiency at part load

- The refrigerant circuit includes several compressors

connected in parallel. At part load, around 99% of the

operating time, only the compressors that are

absolutely necessary operate. At these conditions the

compressors operating are more energy efficient, as

they use the total condenser and evaporator capacity.

- The electronic expansion device (EXV) allows

operation at a lower condensing pressure (EER, COP

and ESEER optimization).

- Dynamic superheat management for better utilization

of the evaporator heat exchange surface.

- Defrost cycle optimization (30RQ)

Reduced maintenance costs

- Maintenance-free scroll compressors

- Fast diagnosis of possible incidents and their history

via the Pro-Dialog Plus control

- HFC-410A refrigerant is easier to use than other

refrigerant blends

Environmental care

Ozone-friendly HFC-410A refrigerant

- Chlorine-free refrigerant of the HFC group with zero

ozone depletion potential

- High-density refrigerant, therefore less refrigerant

required

- Very efficient - gives an increased energy efficiency

ratio

Leak-tight refrigerant circuit

- Brazed refrigerant connections for increased

leaktightness

- Reduction of leaks due to reduced vibration levels and

elimination of capillary tubes (TXVs)

- Verification of pressure transducers and temperature

sensors without transferring refrigerant charge

Superior reliability

State-of-the-art concept

- Cooperation with specialist laboratories and use of

limit simulation tools (finite element calculations) for the

design of the critical components, e.g. motor supports,

suction/discharge piping etc.

Exceptional endurance tests

- Corrosion resistance tests in salt mist in the laboratory

- Accelerated ageing test on components that are

submitted to continuous operation: compressor piping,

fan supports

- Transport simulation test in the laboratory on a

vibrating table.

Pro-Dialog Plus Control

Pro-Dialog Plus combines intelligence with operating simplicity. The control constantly monitors all machine

parameters and precisely manages the operation of compressors, expansion devices, fans and of the

evaporator water pump for optimum energy efficiency.

User-friendly interface

- The new backlighted LCD interface includes a manual control potentiometer to ensure legibility under any

lighting conditions. The information is in clear text and can be displayed in English.

- Unit uses intuitive tree-structure menus, similar to the Internet navigators. They are user-friendly and permit

quick access to the principal operating parameters: number of compressors operating, suction/discharge

pressure, compressor operating hours, set point, air temperature, entering/leaving water temperature.

Advanced control function

- Unit provides different control mode including LOCAL/REMOTE/CCN.

- Remote control function including: Unit ON/OFF, dual set point control, demand limit control, user safety

interlock, water pump control, operation indication, circuit alarm and alert etc.

- Enable automatic reset of leaving water temperature according to return water temperature or outside air

temperature to ensure optimum energy efficiency.

- Control algorithm prevents excessive compressor cycling and permits reduction of the water quantity in the

hydronic circuit (Carrier patent).

- Automatic compressor unloading in case of abnormally high condensing pressure. If an abnomal incident

occurs (e.g. fouled condenser coil, fan failure), Aquasnap continues to operate, but at reduced capacity.

Powerful Diagnostics

- Unit can perform a quick test (manually or automatically) of all unit components and control points to verify

the correct operation of unit

- Real-time monitor all the controls and operation parameter, alarm when necessary.

- Control system includes RS485 serial communication port for remote diagnosis or special diagnosis tools.

Sufficient safety measures

- Password protection in case of mishandling.

- Unit is protected against: compressor reverse, low chilled water temperature, high/low refrigerant pressure,

excessive current, motor overload.

Group control

- Master/slave control of two chillers operating in parallel with operating time equalization and automatic

changeover in case of a unit fault.

- Communication with other Building Management System (BMS) by selecting BacNet/J-Bus/LonTalk

gateway.

Minimum Water Loop Volume

Maximum Water Loop Volume

For better control of leaving water temperature, the water loop minimum capacity is given by the formula:

Capacity = CAP (kW) × N Liters

CAP: Unit’s nominal cooling capacity

Should be greater than 3.5 for better water temperature control

It is often necessary to add a buffer water tank to the circuit in order to achieve the required volume. The tank

must itself be internally baffled in order to ensure proper mixing of the liquid (water or brine). Refer to the

examples below.

The expansion tank of the unit with hydronic module limits the maximum water volume, refer to below sheet:
